No. 209: Periodic Table: 16 Sulphur

T-Rex: T-Rex presents The Periodic Table:
T-Rex: 16 SULPHUR
T-Rex: In 1990 the IUPAC decided to standardise the spelling to "SULFUR". Surprisingly, this did not change the pH level of sulfuric acid.
Utahraptor: Why didn't they also change to FOSFORUS?
T-Rex: That's... actually a really good question. We can confuse ANOTHER whole generation of students.
T-Rex: IUPAC - get on it!
T-Rex: Also: it's yellow. True fact!
